What's next

A roadmap to the future developments of Brainstorm.

Current topics

Functionnal connectivity

Integration of different metrics to study the brain connectivity:
Correlation, coherence, Granger causality, phase locking value
Development of new ways to represent the connectivity between sensors or brain regions

EEG / epilepsy / intra-cranial recordings

Editing the position of intracranial electrodes in the MRI viewer

Source modeling

Computation of equivalent current dipoles
Beamformers

Large scale analysis

Parallel processing: Reduce the computation times using the parallel processing toolbox
Distributed processing: Integrate tools for sending Brainstorm processes on computation clusters

Recordings

RAW file viewer:
- Pre-load next page of recordings
- Documentation: Add definition of bad segments
- 2DLayout: Doesn't work when changing page => need refresh of GlobalData.Preferences.TopoLayoutOptions.TimeWindow
EEG reference/storage:
- Intracranial electrodes: Define in the MRI viewer
- Bad channels that can be specified at the program level (for sites that have permanently bad channels) => AS Dubarry
RAW processing:
- Make it work for all the file formats (at least bandpass filter + sin removal)
- Events: advanced process for recombining. Example: http://www.erpinfo.org/erplab/erplab-documentation/manual/Binlister.html
Colormaps:
- Create a colormap similar to MNE, where extrema are bright
Import data:
- Save properties "baseline" and "resample" at the level of the protocol (to re-use for all the files)
NIRS:
- Add new data type
- Display of sensors by pairs oxy/deoxy (red/blue), overlaid
Images of amplitude: [sensor x time], [trial x time], scout: [trial x time]
- Can be done with Matrix > View as image: extract cluster, concatenate for all trials
2D Layout for multiple conditions
Filtering: Use short FIR filters instead of IIR for bandpass, to limit the ringing
Or allow the users to edit the LowStop parameter in bst_bandpass.

Display

Nicer 2D topographies, standardized
Copy figures to clipboard (with the screencapture function)

Connectivity

Tutorial coherence [1xN]
t-tests on connectivity measures
Graph view:
- Fixed scales for intensity sliders
- Fix zoom in one region
- Text bigger
- Too much data in appdata
Other metrics:
- Coherence by bands: bst_coherence_band_welch.m
- Granger by bands: bst_granger_band.m
- Inter-trial coherence
Work on progress bars

Processes

Use Matlab Coder to optimize some processes: Wavelets, bandpass filter, sinusoid removal
Time-frequency:
- Frequency bands: extended syntax (ex: [2 3 4], 10:5:90, ...)
- How to combine 3 orientations for unconstrained sources
- Display logs as negative
- 2D Layout in spectrum
- Make much faster and more memory efficient (C functions coded by Matti ?)
- Smooth display of TF/PAC maps (option)
- TF scouts: should display average of TF maps
Bandpass: Show warning when using inappropriate high-pass filter (precision too high)
Artifact detection:
- Detection of bad segments in the RAW files (Beth)
- Artifact rejection like SPM: if bad in 20%, bad everywhere
- Test difference between adjacent samples
Distributed processing: Brainstorm that can run without Java
SSP:
- Display warning if changing the ChannelFlag while there is a Projector applied
- Show where the attenuation is projected:
  (sum(IK,2)-sum(SSP(k,:)*IK,2)./sum(IK,2)
Average:
- Remember how many trials were used per channel
- Save standard deviation
- Display standard deviation as a halo around the time series
Co-registration of MEG runs:
- SSP: Group projectors coming from different files
- Finish validation of the method
- Apply to continuous recordings for correcting head movements
Current Source Density (CSD) => Ghislaine
http://psychophysiology.cpmc.columbia.edu/software/CSDtoolbox/index.html
Other processes:
- Detrending
- Moving average
- Max
- Median
- Significance test (Dimitrios, Leo)
- Spatial smoothing: check / document parameters
Contact sheets & movies: use average of time windows instead of single instants, for each picture.
Optical flow

Database

MEG protocols: More flexible organization of the database; sub-conditions to allow different runs X different conditions.
Group matrix files => allow to process matrix files by trial types
Add notes in the folders (text files, visible as nodes in the tree)
Screen captures: save straight to the database
Rename multiple files

Source modeling

Compare: dSPM vs. wMNE+zscore
Finish dipole scanning
Dipole fitting
Stenroos 2014 paper: Include the following methods
- Inner and outer skull surfaces generator from FieldTrip (needs SPM, probably not so different from BST)
- Nolte corrected-sphere model (good model re:Alex)
- Fast BEM models
Visualize Beamformer results:
- Read CTF SAM .svl
- Display as layers in the MRI viewer
Unconstrained sources:
- Compute unconstrained and then project on the normal ?
- Difference and stat should be: norm(A) - norm(B)
- Stat and connectivity: what to do? (re-send email John+Sylvain)
Overlapping spheres: improve the estimation of the spheres for the frontal lobes
Volume grid:
- Scouts 3D
- Test volume sources with all the subsequent processes (timefreq, stat...)
- Optimize: 3D display (better that 9x9 cubes)
- Optimize: vol_dilate (with 26 neighbors)
Magnetic extrapolation: Do the same thing with EEG
Noise covariance matrix:
- Display with figure_image()
- Storage of multiple noise covariance matrices (just like the head models)
- Always save as full, then at inversion time, we can decide between full, heteroskedastic (diagonal) or homoskedastic (i.i.d, scalar)
- Problem of having inividual trials + averages in the condition => Display warning or not?
- Save nAvg in noisecov file, to make it easier to scale to other recordings
- When deploying to other conditions: Apply destination SSP (NoiseCov = SSP . NoiseCov . SSP' )
Sources on surface: Display peak regions over time (time = color) => A.Gramfort
Simulation: synthesize pseudo data-files from a cortex patch (duration, amplitude, noise)
Calculate ImagingKernel * Gain for a scout
EEG Source modeling: Manage references and bipolar montages properly (maybe not necessary)
MEG source modeling: Do reconstruction only for a subset of sensors for estimating dipoles?
Processes compute head model and sources: Additional option to set the file comment

Anatomy

Scouts:
- Display edges in the middle of the faces instead of the vertices
- Project scouts betweens subjects and between hemispheres
- Display scouts in a tree: hemisphere, region, subregion
- Downsample to atlas: allow on timefreq/connect files
- Sort scouts by region in process options
Generate mixed density surfaces
Import / registration:
- Major bug when importing surfaces for an MRI that was re-oriented manually
Use mid-gray instead of pial surface?

Statistics

ANOVA: Use LENA functions
- Output = 1 file per effect, all grouped in a node "ANOVA"
- Display several ANOVA maps (from several files) on one single figure, using a "graphic accumulator", towards which one can send any type of graphic object
Permutation tests:
- t-test only (wilcoxon? sign-test?): paired, equal var, unequal var
  - http://www.adscience.fr/uploads/ckfiles/files/html_files/StatEL/statel_wilcoxon.htm
  - http://www.mathworks.fr/fr/help/stats/signrank.html
  - Less powerful than t-tests
- nb permutations ~ 1000
- maximum statistic over "time" or "time and space"
Permutations / clustering: cf fieldtrip
- http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_timelock
- http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq
Threshold in time: keep only the regions that are significative for contiguous blocks of time, or over a certain number of time points
=> Process that creates a static representation of a temporal window
t-test on volume sources
Paired t-test on unconstrained sources: (convert to flat + Z-score) => AnneSo
- Question of Gaussianity of the samples: take a subset of samples + Kolmogorov-Smirnov / Shapiro-Wilk test
- http://fr.wikipedia.org/wiki/Test_de_Shapiro-Wilk
- http://stats.stackexchange.com/questions/362/what-is-the-difference-between-the-shapiro-wilk-test-of-normality-and-the-kolmog
- http://www.mathworks.fr/fr/help/symbolic/mupad_ug/perform-shapiro-wilk-test.html
- http://www.mathworks.fr/fr/help/symbolic/mupad_ref/stats-swgoft.html
- http://stackoverflow.com/questions/14383115/shapiro-wilk-test-in-matlab
Create icons for Stat/PAC, Stat/Sprectrum, etc.
One sample t-test across subjects

Current bugs

Import anatomy folder menu freezes Matlab on MacOS 10.9.3 / Matlab 2014a
Import anatomy folder menu crashes on MacOSX 10.8.5 / Matlab 2013b
Record tab: Text of epoch number is too big on MacOS
Menu "Use default EEG cap" doesn't work for a multiple selection (setting the same EEG cap for several subjects)
in_bst_data_multi: If trials have different sizes, output is random (the one of the first file)
tree_dependencies: sources files, reprojected on default anatomy; If based on data files that are bad trials, they should be ignored by tree_dependencies, and they are not
Image viewer has some bugs on some systems
Screen capture for reports never works: Find another solution
Screen capture when there is a fading effect in the window manager: captures the window
Close figure with coherence results should hide the "frequency" slider
Problems growing scouts on merged surfaces (Emily)
Edit scout in MRI: small modifications cause huge increase of the scout size

Geeky programming details

Hide Java panels instead of deleting them
mri2scs: convert arguments to meters
Interpolations: Use scatteredInterpolant, griddedInterpolant, triangulation.nearestNeighbor (Matlab 2014b)
bst_warp and channel_project: Use tess_parametrize_new instead of tess_parametrize

Optimize bst_get:
- Now study and subject have necessarily the same folder name
- Replace big switch with separate functions
Progress bar:
- Add different levels (to handle sub-processes)
- Make work correctly with RAW on resting tutorial
- Uniformize calls in bst_process/Run
- Add a "Cancel" button
Line smoothing / anti-aliasing (time series figures)
Fix all the 'todo' blocks in the code
Replace handle "0" with bst_get('groot')
At the end of bst_startup in compiled mode, replace loop with waitfor(jFrame)

 * Hide Java panels instead of deleting them
 * mri2scs: convert arguments to meters
 * Interpolations: Use scatteredInterpolant, griddedInterpolant, triangulation.nearestNeighbor (Matlab 2014b)
-Line 150:
+Line 241:
- * Testing functions: test_ctf "folder" / test_neuromag "folder" / test "folder" => Alex
 * Bug in_bst_data_multi: If trials have different sizes, output is random (the one of the first file)...
-Line 153:
+Line 242:
- * Rewrite all GUI functions with gui_component
 * Remove field "!BrainStormSubject" in the studies file: force same folder name for anat & data
 * Allow protocols with same folder for anat and data
 * Ensure that all the loaded and saved filenames are in "unix" format
 * Use parfor: When not available, replace directly all the "parfor" with "for" in file.m
 * Use Matlab GPU toolbox
 * Re-use panels instead of delete+create again
 * Optimize bst_read_events_track
 * Write shepards.m with new algorithm for nearest neighbors
 * Use tesselations_stat and tesselations_outwards to clean surfaces
 * Movies: Use JAVE (Java)
 * Screen captures: Use Yair Altman functions (in Matlab Central)
